To all whom it'may concern: ;device,' which has its front or outer portion Be itknown that I, WILLIAM M.

The shoulder 10 is of which the following is a specification. formed by recessing the enlarged portion or The invention relates to improvements in head of the locking device 9, and when the car-couplings. catch 7 swings inward or rearward by the The object of the present invention is to means hereinafter described its beveled end [0 improve the construction of car: couplings 8 is adapted to engage and lift the locking and to provide a simple, inexpensive, and of device 9, which is hinged at its lower end at ficient one capable of coupling automatically'f 11 to the top of the draw-head. .The shank when two cars come together and adapted to 12 of thelocking device rests upon the upper be readily uncoupled and secured in a'posiface of the draw-head when it is in the posi- I 5 tion that will admit of automatic uncoupling. tionshown in Fig. 2, and the head or outer The invention consists in the construction portion of the lockin g deviceis provided with and novel combination and "arrangement of an outwardly-extending arm 13, which rests parts, hereinafter fully described, illustrated upon the upper face of the front portion of in the accompanying drawings, and pointed the top of the draw-head. 20 out in the claims hereto appended. The L-shaped catch is adapted to be swung In the drawings, Figure 1 is a perspective rearward by the link 6 entering. the drawview of acar-coupling constructed in accordhead and engaging the arm 14, and the said ance with this invention. Fig. 2 is'a longi link is provided at its endswith openings 15 tudinal sectional view of thesame. Fig. 3 is to receive the arm 7. The transverse shaft 2 5 a detail perspective view of the locking de is provided at one end with an arm 16 to en- 7 5 vice. Fig. 4 is a similar view of acatch and able it tobe turned by hand, and the arm 14 its shaft. Fig. 5 is "a detail perspective view ,0f the catch lies below the plane of the upper of the rock-shaft. Fig. 6 is a transverse 'secface of the bottom of the draw head when the tional view of the car-coupling. catch is in the position shown in Fig. 2.

The arm opening with a longitudinal recess 3, in which 19 may be connected with any suitable operis mounted an L shaped clutch 4, fulcrumed ating mechanism for enabling the operation at its angle on a transverse shaft 5, which is of uncoupling to be performed from the top mounted in suitable bearings or openings of or sides of a car or the platform of a coach,

0 the draw-head. One arm of the catch is or it may be simply operated by hand. The adapted to engage a link 6, as clearly illuscrank bend of the rock-shaft extends'through trated in Fig. 2 of the accompanying drawan approximately-L-shaped slot 20 of the ings, and this arm 7, which is provided with locking device 9, and this slot is provided a beveledend 8, is held in avertical position with approximately vertical and horizontal 5 in engagement with the link 6 bya locking debranches, the horizontal branch being adapt- 5 vice 9, located atthe top of the draw-head and ed to receive the crank-bend of the rock-shaft extending longitudinally thereof, as clearly when the latter is rotated, whereby the lock illustrated in Fig. 2 of the accompanying ing device is lifted out of engagement with drawings. The draw-head is provided at its the arm 7 of the L-shaped catch, and the said 50 top withalongitudinal slot 9,and the locking rock-shaft is adapted. to retain the locking Ioo device in an elevated position to arrange the parts so thatthe link will be permitted to leave the draw-head at any time. This construction enables the car-coupling to be set 5 for 'u-ncoupling without actually separating The vertical slot or branch enables V the cars. the loc-kin-g deviceto be swung upward autotuati-ng the rock-shaft, whereby the looking to device will be prevented from binding or re maining in an elevated position.

It will be seen that the car-coupling is exceedingly simple and inexpensive in construction; that it is positive, reliable, and automatic in its operation, and that the rock=shaf t is adapted to support the locking device in an elevated position for releasing the link.. It will also be apparent that the locking de vice is adapted to swing upward independ- 2o ent-ly of the rock-shaft, so that there will be no liability of the said rock-shaft accidentally holding the locking device in an elevated position. V Whatisclaimed is 1. Acar-coupling comprising adraw-he'ad, an L-shaped catch pivotally' mounted atlthe bottom ot the draw-head, a hinged locking de= vice arranged at the top of the draw-head in position for engaging the catch, saidlockin'g 3o device bein g provided with an'approxi mately L.-shaped slot, and a rock-shaft mounted on the. dra'w h'ead and engaging the slot and adapted to hold the. locking device in an elevated position, said slot also permitting the locking device to move independently of the.

rock-shaft, substantially as described.

2. A car-coupling comprising a draw-head,

an L-shaped catch pivotally mounted at the bottom .of the draw-head, a locking device hinged at the top of the draw-head "for engag- 6 ing the catch and provided with an approximately L-shaped slot, and a transverse rockshaft mounted on the draw-head and pro} vided with a crank-bend extending through the L-s'hapedslot, substantially as andfor the purpose described; 7 matically by the li-shaped catch without acv p p g I a catch pivotally mounted within the draw- 3. A car-coupl ng comprising a draw-head,

head at the bottom thereof, a locking device 7 arranged at the top of the draw-head and adapted to engage the catch, said locking device being provided with an approximately L-shaped slot, and a rock-shaft engaging the k-shaped slot of the locking device and adapt= ed to support the latter in an elevated posi tion, substantially as and for the purpose described.

4. A car-couplingComprising a draw=head provided at itstop with a slot, a catch mount ed within the draw-head at the bottom there=' I ported by the upper face of the drawhead atpointsin advance and in rear'of-th'e slot and 'being provi'ded with an enlarged intermedi= 'ate portion extending downward through the slot and engaging the said catch,rsubstan'- tially as described.
